Developing a Claim

1 answer:

4 0

To develop a claim on the topic of simultaneous co-evolution in the biosphere, it is necessary to carry out further research on the topic.

<h3>What is coevolution</h3>

It can be defined as the simultaneous evolution of adaptations of two species that interact where one responds to the evolution of the other.

<h3> How to write an effective claim</h3>

It is necessary to rely on reliable sources to generate more consistent ideas that generate greater reflection on the proposed theme. You can base your position on relevant articles, scholars or citations on the topic to generate a more objective and efective construction.

Oil having a specific gravity of 0.9 is pumped as illustrated with a water jet pump. The water volume flowrate is 1 m3 /s. The w

love history [14]

Answer:

The rate at which the pump moves oil is 1 m³/s

Explanation:

Assumptions:

there is steady-state flow

oil and water are incompressible

first fluid is water, second fluid is oil and third fluid is the mixture of oil and water.

$\rho_1Q_1 + \rho_2Q_2 = \rho_3Q_3 -------equation (i)$

where;

ρ is the fluid density

Q is the volumetric flow rate

$Q_1 + Q_2 = Q_3--------equation (ii)$

Substitute in Q₃ in equation i

$\rho_1Q_1 + \rho_2Q_2 = \rho_3(Q_1 +Q_2)$

divide through by ρ₁

$\frac{\rho_1Q_1}{\rho_1}+ \frac{\rho_2Q_2}{\rho_1} =\frac{ \rho_3(Q_1 +Q_2)}{\rho_1}\\\\Note; \frac{\rho_2}{\rho_1} = \gamma_2 \ and \ \frac{\rho_3}{\rho_1} = \gamma_3\\\\Q_1 + \gamma_2Q_2 = \gamma_3(Q_1+Q_2)$

Make Q₂ the subject of the formula

$Q_2 = \frac{Q_1(1- \gamma_3)}{\gamma_3-\gamma_2} = \frac{1 (\frac{m^3}{s}) (1-0.95)}{0.95-0.9} = 1 \ \frac{m^3}{s}$

Therefore, the rate at which the pump moves oil is 1 m³/s

A falling ball of mass 0.5 kg experiences a downward force due to gravity of mg (where g = 9.8 m/s2) and an upward force of air

schepotkina [342]

Applying Newton's Second Law of Motion, the acceleration of the ball is 16.8 $m/s^2$

<u>Given the following data:</u>

Mass = 0.5 kg

Acceleration due to gravity = 9.8 $m/s^2$

Upward force = 3.5 N.

To find ball's acceleration, we would apply Newton's Second Law of Motion:

First of all, we would determine the net force acting on the ball.

$Net \; force = Upward\;force + Downward\;force$

$Downward\;force = 0.5$ × $9.8$

Downward force = 4.9 N

$Net \; force = 3.5 + 4.9$

Net force = 8.4 N

Mathematically, Newton's Second Law of Motion is given by this formula;

$Acceleration = \frac{Net\;force}{Mass}\\\\Acceleration = \frac{8.4}{0.5}$

<em>Acceleration = 16.8 </em> $m/s^2$ <em />

Therefore, the acceleration of the ball is 16.8 $m/s^2$

Can anyone pls help me with this I’ll appreciate it. I’m trying to study for a test but I don’t know the answer to this.

forsale [732]

Answer:

okay so what you will do is where is says red giant you will write all about what it talks about red giants only, and the box plantary nebulas you will write about what is says about only planetary nebulas. x- hope this helps :)

A circuit has a current of 1.2 A. If the voltage decreases to one third of its original amount while the resistance remains cons

Katen [24]

When resistance is constant, current is proportional to voltage. When 1/3 the voltage is applied, 1/3 the current will result.

(1/3)*(1.2 A) = 0.4 A

The resulting current will be 0.4 A.

mylen [45]

To point out that relationships call for regular maintenance. Cars need regular oil checkups and such and so do relationships.

Hope this helps :)
